One of the features of wireless sensor networks is that the nodes in this network have limited power sources. Therefore, assessment of energy consumption in these networks is very important. What has been common practice has been the use of traditional simulators to evaluate the energy consumption of the nodes in these networks. Simulators often have problems such as fluctuating output values i...

This paper presents exergy and exergoeconomic analysis and parametric study of a Diesel engine based Combined Heat and Power (CHP) system that produces 277 kW of electricity and 282 kW of heat. For this purpose, the CHP system is first thermodynamically analyzed through energy and exergy. Then cost balances and auxiliary equations are applied to subsystems. The exergoeconomic analysis is based ...

In recent years, techniques of output combination from multiple speech recognizers for improved overall performance have gained popularity. Most commonly, the combined systems are established independently. This paper describes our attempt to directly target joint system performance in the discriminative training objective of acoustic model parameter estimation. It also states first promising r...

Background: Radiosurgery is a focal brain irradiation technique that delivers, usually in a single session, high dose of ionizing radiation. The presence of lateral electronic disequilibrium and steep dose gradients in small fields demands special attention to the selection of a suitable detector with respect to its size, composition and response. Materials and Methods : Small circular fields w...

-----------------------------------------------------ABSTRACT----------------------------------------------------In recent years, multilevel inverters have gained much attention in the application areas of medium voltage and high power owing to their various advantages such as lower common mode voltage, lower voltage stress on power switches, lower dv/dt ratio to supply lower harmonic contents ...

The article describes a colour based recognition system with three novel features. Firstly, the proposed system can operate in environments where spectral characteristics of illumination change in both space and time. Secondly, benefits in terms of speed and quality of output are gained by focusing processing to areas of salient colour. Finally, an automatic model acquisition procedure allows r...

Neural network techniques have been demonstrated to be successful at segmenting the retinal vasculature in fundus images; however, occasionally there are cases where a haemorrhage is misclassified as a vessel. The combination of the output from the neural network and information gained from the application of a tracking algorithm, based upon a matched filter, is shown to be a promising techniqu...
